Overview of this book

Google Cloud Platform is one of the three major cloud providers in the industry, exhibiting great leadership in application modernization and data management. This book provides a comprehensive introduction for those who are new to cloud development and shows you how to use the tools to create cloud-native applications by integrating the technologies used by Google. The book starts by taking you through the basic programming concepts and security fundamentals necessary for developing in Google Cloud. You'll then discover best practices for developing and deploying applications in the cloud using different components offered by Google Cloud Platform such as Cloud Functions, Google App Engine, Cloud Run, and other GCP technologies. As you advance, you'll learn the basics of cloud storage and choosing the best options for storing different kinds of data as well as understand what site reliability engineers do. In the last part, you'll work on a sample case study of Hip Local, a community application designed to facilitate communication between people nearby, created by the Google Cloud team. By the end of this guide, you'll have learned how to design, develop, and deploy an end-to-end application on the Google Cloud Platform.

Application modernization best practices

To use all the benefits that GCP offers, is it not enough just to move your monolithic application to the cloud. It is also necessary to perform refactoring processes to delegate the greatest amount of responsibility to self-managed cloud services, and also allow our application to have elasticity and automatic recovery capabilities.

To achieve this goal, in this section, we will review the steps we must follow to refactor a monolithic application to a modern architecture and microservices design pattern.

Modern application design

In a design pattern oriented toward microservices, there are three fundamental elements that allow us to uncouple the responsibilities of the applications as much as possible, and thus reduce the amount of code to modify when it is necessary to make changes:
